Description of problem:
Gnome-software makes system hard freeze.
Version-Release number of selected component (if applicable):
gnome-software-3.18.3-1.fc23.x86_64
How reproducible:
allways
Steps to Reproduce:
1. Start Software
2. wait 2-3 seconds
3. System freezes hard, if in this moment was disk activity, hard disk LED remains lit
Actual results:
System not responding in any way (e.g. can not switch to virtual console, no ping answer etc)
Expected results:
Software works as expected or at least not hangs computer.
Additional info:
Hardware- Lenovo X61, 2 GB RAM, Intel 965GM graphics. This is absolute vanilla install (x64 live image + updates, no additional software or repos, did fresh install because i was unable solve same problem after upgrading F22>F23). There is no traces in logs. DNF / rpm works O.K. using command prompt.
Bug is not reproducable in my other F23 systems (all x64).

Another idea is that fwupd might be poking the hardware the wrong way. Does it work better if you rm /usr/lib64/gs-plugins-8/libgs_plugin_fwupd.so and killall gnome-software to make sure it's not already running and start it again?

What does this report on those systems:
find /sys/devices -name "rom"
Also, can you find out *which" rom hangs the system doing "echo 1 > the_long_sysfs_path" and then "cat the_long_sysfs_path > /dev/null" -- thanks!

This bit me pretty hard when upgrading Fedora 23 to Fedora 24.
After 'dnf system-upgrade reboot' the machine would just freeze at boot. I also had the issue of gnome-software freezing my system on Fedora 23.
It was hard to locate this issue, as journalctl didn't show anything AND the boot process did proceed a while longer after fwupd was started, so it wasn't the last thing that happened during the boot that caused the freeze.
enableOptionROM=false sorted it for me as well.
My machine is a stationary core i5 with a GeForce 200 running neuveau (though I had the same issue with gnome-software when I ran the nVidia proprietary driver).

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
of '23'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.
Thank you for reporting this bug and we are sorry it could not be fixed.
